Chapter 5.1: Structure of Alkenes

Question 1

Define cis, trans isomerism

Answer 1

stereoisomers that have the same connectivity but a different arrangement of their atoms in space as a result of the presence of either a ring or a carbon-carbon double bond

Question 2

What are stereoisomers that have the same connectivity but a different arrangement of their atoms in space as a result of the presence of either a ring or a carbon-carbon double bond?

Answer 2

cis, trans isomerism

Question 3

What are two characteristics of alkenes? (Hint: bond and electron density)

Answer 3

• Double bond cannot rotate

* Electron density is above and below bond axis thus available to interact with other molecules
